The enthalpies of combustion of C(s), H2(g) and C4H9OH(l) (in kJ mol-1) are as follows

C(s) + O2(g) ⟶ CO2(g) ∆H = a

H2(g) + ½O2(g) ⟶ H2O(l) ∆H = b

C4H9OH(l) + 6O2(g) ⟶ 4CO2(g) + 5H2O(l) ∆H=c

What is the enthalpy change for the reaction shown below?

4C(g) + 5H2(l) + ½O2(g) ⟶ C4H9OH(l)

c – 4a – 5b

2a + 10b - c

4a + 5b - c

2a + 5b + c
